MEMBER FOR SHORES.

Applicationfiled August 22, 1925. Serial No. 51,764.

The present invention relatesto head'members for shores. 1

Shores such as are used for building construction are elongated members, and in order that the bearing area at the extremity may be relatively large, it is common to provide a head member. Head members for the purpose are frequently very bulky, and the cost of transportation and handling is relatively high. Head members as commonly known and used have the further disadvantage that they are heavy, inconvenient in use, and'are frequently insecure.

An object of the presentinvention is to provide a head member for a shore, which head member will fit the common type of shore, which may conveniently be secured thereto, and which may conveniently be detached therefrom.

A further object isto provide a head mem her for shores which is sturdy, light in weight and small in bulk.

A further object is to provide a mountable head member for a shore, which-will stand long continued hard usage without ,material depreciation, and which is adapted for use with holding means such as are readily procurable in the market.

A further object is to provide a head member for shores which is cheap to manufacture and which-will effectively serve the needs of commercial operation.

Further objects will appear as the descrip' tion' proceeds.

Referring to the d awings- I Figure 1 is a fragmentary View illustrating a portion of a shore, a member supported by said shore and a head member for said shore, which head member embodies the pri uciples of the present invention.

Figure 2 is a view in side elevation, partly shown in section, of the structure shown in Figure 1.

Figure 5 is a sectional view taken along the plane indicated by the arrows 5-5 of Figure 3.

Figure 6 is a sectional view taken along the plane indicated by the arrows 6-6 of Figure 1.

Figure 7 is a perspective view of a spike or nail of common type which may be used m the pract ce of the present invention.

A shore 1s indlcated by the numeral 1,

which shore is indicated in the usual form as including an elongated timber of square cross-section. Timbers known in the art as ix ls are commonly used. A member-to be supported is indicated by numeral 2. :In order to provide abroad bearing surface, the shore 1 provided with a head member. which is indicated as a whole byithe numeral 3. Said head member, according to the present invention, involves a socket portion for receiving an extremity of theshore 1, and is provided with abroad bearing portion for contactwith the member to be supported.

'According-to the present invention, the socket portion referred to 150161110 1761 con-,

formation and cooperates with nails or spikes of well-known construction or other wedgeshaped members for securely holding the head member Bupon the end of the shore.

The socket portion referred to for receiving thcend or the shore 1 is indicated; on

. the drawings by theuumeral 4. Said socket portion 1 has the opposed side walls 55, which may have substantially plane inner surfaces spaced apart a sufficient distance to slidably receive the shore 1. Theintermediate opposed walls 6-6 are provided with the grooves 7-7, two grooves 7-7 being illustrated in each of the walls -6.6. Said walls 66 are spaced apart asufiieient distance toslidably receive the shore 1, and the grooves 7-7 are adapted to receive nails or other wedge-shaped members 88. The

upper part of thesocket portion lis provided with the inturned walls 9-9, which are disposed upon the end of the shore 1 and provide stops for preventing head member 3 from sliding downwardly upon the shore 1. Socket portion 1 is provided with the outstanding flanges or wings 10- 10, which may be reinforced by means of ribs 111l. The head member 3 may be cast or forged steel or iron and should be of sufficiently, tough and strong material to avoid breakage in service.

The nails or other wedge-shaped members 88 are preferably of more than sufficient length to extend through both side walls 5-5 of the socket portion 4-, apertures 12-12 being provided in said side walls 5-5 for permitting the passage of said members 88.

The grooves 77 should be. of such a depth, and the size of the members 88 should be lll) such, that when members 88 are inserted along one side of the socket portion 4, said members will, guided by the grooves 7-7, jam the material of the shore 1 to such an extent that the head member 3 will be secured against removal from the shore 1. The walls 66 will be spaced apart at such a distance that when a new timber is being used, members 88 on only one side of the socket portion 4 will be sufiicient to produce all the locking action required. When old timbers are being used, it may be found advantageous to use members 8 on both sides of the socket portion 4.

It has been stated above that the nails or other wedge-shaped members 88 should be of more than sufiicient length to extend through the two side walls 5 5 of the socket portion l. By reason of this construction, after said members 88 are driven home, the removal thereof is greatly simplified, it being a simple matter to tap same on the point ends thereof. In order to simplify the matter of removal of the members 8-8, it is preferred to use tapered nails, the type knownas cut nails being readily purchasable in the open market and being very well adapted for this purpose, though,

of course, any other preferred Wedgingmember may be used if desired. By reason of the tapered construction, when said nails are tapped at their point ends, they will become freed from the material of the timber to a sufficient extent that said nails" may be readily removed Without the use of any par ticular tools for that purpose. The nails.

or other wedging members 8-8 have a biting effect upon the wooden shore, and there fore produce a locking effect to prevent axial movement between the head member and the shore.

The present invention provides a head member for shores which provides a broad bearing surface, which is relatively light in weight, small in bulk, and which may be attached to a shore and detached therefrom with a maximum of convenience. The life of the illustrated embodiment of the present invention should be practically unlimited, provided tough material is used in the manufacture thereof. Inasmuch as cut nails suitable for the purpose of attaching the head member to the shore may be readily purchased anywhere in the United .States, no difiiculties due to wear on nails need be encountered. The problem of transporting the head members is ve'r greatly simplified, itbeing possible to carry sufiicient head members for a large job in a single truck.

Though a preferred embodiment of the present invention has been described in detail, many modifications will occur to those skilledin the art. It is intended to cover all such modifications that fall within the scope of the appended claims.

IVhat is claimed is:

1. In combination, a wooden shore, a head member therefor, and attaching means for attaching said head member to said shore, said head member comprising a bearing portion and a socket portion, said socket portion being square in cross section, opposed inner walls being parallel with one another, one of said inner walls being pro vided with agroove and a wedging member extending beyond the extremities of said socket portion, said Wedging member being disposed in jamming relationship between said socket portion and said shore, whereby to have a biting effect upon said wooden.

shore toproduce a locking effect to prevent.

said head member axial movement between and said shore. I i i 2. In combination, a wooden shore,a head member therefor, and means for attaching said head member to said shore, said head member comprising a socket portion square incross section, opposedwalls being parallel, the four Walls defining said square cross section being adapted to cooperate with the sides of said shore, said socket portion having a portion adapted'to abutagainst the end of said shore, two of said four walls being substantially plane, another of said walls being provided with a groove, said at tachmg means comprising a wedgmg member adapted to lie in said groove and to have jamming relationship with said otherwall and said shore, said wedging member being of such length that the extremities thereof extend beyond the outlines of said socket.
